thanks. and plex will be able to play all the mkv and mp4 files on the vizio costar? (not the roku...)
I have Roku2's in 2 bedrooms and they play mkv and mp4 files just fine via PLex.
From what I've read, most implementations of DLNA servers can be frustrating and liminiting to use. Some formats not recognised or not playing properly. Before I setup Plex I investigated using DLNA as my BluRay player supports a version of it, and from what I researched it was hit or miss regarding what files and codecs it would play.
Plex will play most anything and to the casual end user gives a great experience, with nice program art and cataloging of TV shows and movies. My GF and daughter wouldn't know a mkv from the NBA but they have no issues at all watching content on the Roku's via Plex.
